I CARJVHEEL SKID-SHOE.

Specification of Letters Patent. Patented J 11119 15, 1920,

Application fiIed September 23, 1919.. Serial No. 325,706.

To all whom it may concern:

Be it known that I, BENJAMAN J; BUnLL, a citizen of the United States residin at Reading, in the county: of Berks and tate Pennsylvania, have invented certain new and useful Improvements in Car-Wheel Skid-Shoeacf which the following is a means for supplying said lubricant to its.

specification.

This invention relates to improvements'in car wheel skld shoes and more particularly to that class of devices. adapted to slide on the rail and be positioned between the rail and wheel to lift and maintainthe wheel off of the track when the same has been damaged and it is necessary to get. the car back to the shop for repairs without the removing or turning of the car wheel.

The principal object of theinvention is to provide a wheel skid capable of being used in both a forward and backward direction, thus making the same substantially reversible and it is immaterial whether the car is being drawn ahead or backed during itstravelto the yard .After the device has. 25

once been appliedto the Wheel the same is substantially locked; thereon and the car can be run in either direction, as will be hereinafter morefully described.

I Another feature iof applicants invention is themanner of locking the car wheel in place on the devicesothat thewheel cannot be displaced therefrom 1 when the car is moved in a forward directionjor backward direction, as distinguished from the. older type ofzskids capable. of use only infone direction without shifting or completely turningQthe skid around; 1 Another object of the invention-is to pro vide a self lubricating wheel skid in ord'er that the same might ride the rail with the least amount of friction and wear and,

thereby greatly increasing'the efiicien'cy'of the device, particular reference beinghad to the lubricating of the forward or rounded end of the shoe, sothat when in use? and weight. is brought against the forward chock the lubrication of this forwardiportion will prevent thebinding or sticking of the shoe in case the same should be tilted forward slightly during its initial movement. l 1..

Briefly stated, applicants. device comprises substantially a hollow or recessed casting in the form of a wheel skid shoe having a bearing upon the track through on the rail. 1

out its entire length, and adapted to be inserted under the car wheel between the rail,

and the wheel, to support the wheel, said device belng Pl'OVlClBClWlth means for locking the car wheel against forward and backward movement with respect to the skid,

said skid also containing a lubricant, and

rail engaging surface to reduce the fric-i tional contact with the rail and minimize the wear on the device when in operation. With the foregoing and other objects in view, the invention resides inthe combination and arrangement of parts and the details of construction hereinafter set forth and claimed, it being understood that changes in the precise embodiment of invention, herein disclosed, can be made within the scope of the claims without dc; parting. from the spirit of the invention.

Referring to; the drawings in "which like body portionof elongated formation hav-.

ing a rail engaged surface 2 comprising the bottom, ELIlClrZL top 3. upon which is supported the car wheel whenthe skid is. in operative position. a l" At one end ofthe main, body hportion, which for the purpose of description will be calledtheiforward end, there is an upstanding or raised membencomprisinga chock or stop .4, said chock having an inner curve 5Kof a general contour corresponding tothe outer periphery of acar wheelu The oppo site face of the chock f is also curved as at 6, the lower portion of which,.by a reverse curve, rounding into a nose 7uslightly ele vated in aplane abovethe straight portion of the bottom 2 and also slightly "above the toprof the rail when the skid is in position the lubricant con At the opposite or rear end of the elongated body portion 1 there isprovided a reduced portion in the form of a bifurcated tongue 9 having an incline 10 upon which the car wheel rides when being elevated from the rail to position on the main body of the skid.

Adjoining the upper part of the incline 10 on the after end of the'straight portion of thetop 3, there is provided a series of transverse notches or grooves 11 for the purpose as will be hereinafter more fully described. Positioned upon this after end vthere is an adjustable chock 12 having a forward incline face 13 and a bottom face provided with grooves 14 corresponding with' the grooves 11 of the main body portion, the grooves 11 and 14 thus forming an interlocking engagement when the chock is in' its final or adjusted position. To maintain the chock 1n itsadjusted'position andcooperating with the notches or grooves 11' and 14, there is a bolt or slmilar fastening 15 passing'through the chock and the after end of the main body, portion of the'skid shoe. Preferably, .the nut 16. on the bolt is set up against the upper portion of the chock 12 and the head of said bolt underlies the grooved portion 11 of the after end of the skid so that said nut may be readily manipulated, which construction is obvious. To facilitate easy and ready adjustments of the chock 12 carrying the fastening 15, the rear or tapered end of the device isbifurcated, providing an elongated opening 16 running from the extreme rear end of the device up to and including the-notched portion 11 as clearly shown in the drawings. Along the inner edges of the bifurcated tongue'9, forming the opening 16, there are provided angular shoulders or rabbets 17.

These rabbets are to accommodatethe head of the fastening or bolt during the operation of sliding the adjustable chock in position onthe skid, and also act as a stop for the head of said bolt when setting up the nut after the chock has been placed in the desired position. i

Extending downwardly from the inner side of the device and about midway thereof is a dependent flange 8 which, when the skid isbeing drawn along the rail, m'aintains'the device on the rail, acting in a manner similar to a flange'gon 'a'car wheel, which will be plain to one skilled in the art.

For the purpose of supplying a lubricant to the rail between the topof the rail and the railengagingsurface of the wheel skid, there are provided a series of cavities or recesses 19 for containing oil or greasein any preferred form, each of said lubricant containing cavities having a feed opening 20 througlrwhich the. oil or grease passes to therail. In addition to the above-mentioned' recesses or cavities and in order to function as the openings 20. The lubricate ing of this forward end portion of the skid shoe is particularly desirable as it affords easy riding of the shoe 'OVBF UHGYBHTEllS and similar obstructions and also prevents jamming or sticking of the shoe during the initial movement of said shoe when the device is in operation. r Fig. 4 lllustr'ates another manner of forming thetransverse grooves ll, wherein the said grooves do not extend all the way to the edge of the skid, but leave asmooth portion 18*along each side thereof. Of course,

if this construction is used,the cooperatinggrooves in the movable chock would also,

have to be changed to conform thereto.

From the foregolng descrlption the operation of the deviceis obvious. Placing-the skid shoe on a track in front of a-broken' wheel the car is drawn forward and the wheel drawn uprthe incline onto the straight portion of the. device until it, engages the forward stop. The adjustable c'hockis then placed in position on the skid 'with' its grooved under face in engagement with the grooved 7 after end of the elongated body;

portion and the forward inclined face of the movable chock ine'ngagement with the after side ofthe wheel tread. During this adjustment the locking boltfis guided in the opening formed by the bifurcated tongue,

the head of the bolt fitting in the angulargrooves or rabbets along theinner edges of thebifurcated tongue'as clearly show-n in the drawing. After adjusting the movable chockto the wheel it is only necessary to set up on the nut of the flockingbolt and the device is ready for use. T I 7 What I claim is: g I 1. In a car wheel skid shoe, a main body portion having on its inner lower edge a rail engaging flange, an integral raised portion at one end, and an adjustable memberor chock atjthe other end 'and'cooperating grooves'on' the chock and main body portion for secur ing said'chock inits adjusted position.

i 2. In a car wheel skid shoe a main body portion having on its inner lower edge a rail engaging flange, an integral raised portion at one end, achock at the other end cooperating grooves on thechock and main body portion for lockingsaid chock to said main body portion, and means for maintaining said check and main body portion in their interlocked position.

lit

3. In a car wheel skid shoe, a main body portion, an integral raised portion at one end, an adjustable chock at the opposite end and cooperating means on said main body portion and adjustable chock for locking said chock in its adjustable position.

4. In a car wheel skid shoe, a main body portion provided with a series of recesses, a lubricant carried within said recesses, means for feeding the lubricant to the rail from said recesses and means carried by said main body portion for securing the wheel thereon against both forward and backward movement.

5. In a car wheel skid shoe, an elongated main body portion, a substantially hollow integral raised portion at one end adapted to contain a lubricant, an adjustable chock at the opposite end, and means for feeding the lubricant from said hollow end portion, to the rail.

6. In a car wheel skid shoe, a main body portion provided with a series of recesses, a substantially hollow integral raised end portion, said recesses and hollow end portion adapted to contain a lubricant, and openings through the rail engaging surface of the decesses for supplying a lubricant between the rail engaging surface of the device and the rail.

8. In a car wheel skid shoe adapted to be positioned between the rail and the car wheel, and main body portion provided With a series of recesses, and substantially hollow integral raised end portion, said recesses and hollow end portion adapted to contain a lubricant, openings through the rail engaging surface of the device to said recesses for feeding the lubricant to the rail during the operation of the device, and means for locking the car wheel on said main body portion against both forward and backward movement.
